Compare any two graphics cards:
GeForce 8600 GT 256MB DDR2 vs GeForce 940M
IntroThe GeForce 8600 GT 256MB DDR2 comes with core clock speeds of 540 MHz on the GPU, and 400 MHz on the 256 MB of DDR2 memory. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.Compare all that to the GeForce 940M, which comes with GPU core speed of 1072 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 64-bit bus. It also is comprised of 384 Stream Processors, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe GeForce 940M should theoretically be much faster than the GeForce 8600 GT 256MB DDR2 in general. (explain)
Texel RateThe GeForce 940M should be quite a bit (about 198%) faster with regards to AF than the GeForce 8600 GT 256MB DDR2. (explain)
Pixel RateThe GeForce 940M will be quite a bit (about 99%) better at AA than the GeForce 8600 GT 256MB DDR2, and also will be capable of handling higher resolutions better. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
